During the last week Chandra completed the observing schedule as
planned.

A real-time procedure was executed on Oct 1 to test an update to the
MUPS thruster firing parameters. The flight software was temporarily
patched with the updated parameters for a short, scheduled MUPS
thruster firing. The thruster firing performed as expected. The firing
parameter update was planned pre-launch as a maintenance activity to
compensate for the decrease in thruster impulse with fuel use. As an
additional benefit the updated firing parameters are expected to
decrease susceptibility to thermal choking in the thrusters.
